only one of the 7 vents on my pod in sucking in the waist is that ok or should they all suck in the waist from the fish? :notsure: :notsure: :notsure: :notsure:
Take the sponges out, they are nitrate factories. I am in the process of making the rear of my 'Pod a refuge. I ordered the rubble rock and chaeto, will be in next week. Also, take out the ceramic rings and bioballs. About the vents, mine has a slider thing on it. You may want to check that, it may be in a position that is blocking them.
